Objective : To evaluate the effect of second-line conservative surgery on in vitro fertilization (IVF) outcome in comparison with IVF without second-line surgery in infertile women with ovarian endometrioma recurrence after primary conservative surgery.
Methods : In this retrospective cohort study, 121 consecutive IVF/intracytoplasmic sperm injection cycles that were performed after second-line surgery (n=53) or without second-line surgery (control group, n=68) between January 2006 and December 2011 in 121 infertile women with ovarian endometrioma(s) recurrence after primary conservative surgery for moderate to severe endometriosis were included. The two groups were compared in terms of controlled ovarian stimulation and IVF outcomes.
Results : There were no differences in patients’ characteristics between the two groups. Total dose and days of gonadotropins administered were significantly higher in the second-line surgery group than in the control group (P<0.001, P=0.008). The numbers of oocytes retrieved, mature oocytes and grade 1 or 2 embryos were significantly lower in the second-line surgery group (P=0.007, P=0.001, P<0.001, respectively). Clinical pregnancy rate per cycle and embryo implantation rate were also significantly lower in the second-line surgery group of 24.5% and 11.8% compared with 48.5% and 25.3% in the control group (P=0.008, P=0.005, respectively).
Conclusion : Ovarian response to controlled ovarian stimulation and IVF outcome after second-line surgery is worse than those in IVF cycles without second-line surgery in infertile women with ovarian endometrioma recurrence after primary surgery for moderate or severe endometriosis.
